8 Claims. (Cl. 9168l My invention relates particularly to a wood fioorfinish and has in view to provide a composition that can be applied tonew fioors or can be used for refinishing old fioors.

Most of the floor finishes that are now used provide only a surfaceprotection to wood and when a worn spot is refinished in part, it showsthe laps. With my finish, however, worn spots can be refinished withordinary labor and without showing laps.

My finish, instead of being'merely a surface protection, penetrates thewood, hardens the surface and the finish and the wood wear together.

In the preparation of the finish, I first prepare a composition of thefollowing ingredients preferably in the approximate proportionsindicated.

Linseed oil 313 Gallons China-wood oil 94 Gallons A mixture consistingof 60% limed rosin and 40% varnish makers and painters naphtha 130Gallons Parafiin wax 724 Pounds Zinc stearate 50 Pounds Varnish makersand painters naphtha 365 Gallons crystals of zinc stearate, -thusstrengthening the skin.

When the paraffin wax is dissolved in the solvent, together with theskin forming oils, the wax will be deposited first and on top will bethe substantially pore proof skin. The paraflin Wax usually crystallizesin needle crystals but the presence of the gloss oil produces anamorphous wax. The gloss oil used contains of limed rosin and 40%varnish makers and painters naphtha. The gumlike characteristics of therosin prevents the crystallization of the wax and produces asubstantially continuous amorphous film.

Other waxes, particularly Japan wax and ceresin wax, could be usedinstead of pa'rafin wax.

Other gums could be used for the rosin in th gloss oil such as kauri,Congo, dammar and Zanzibar gums.

Other solvents could be used such as oleum spirits, benzol, toluol,turpentine, etc.

Other oils could be used in place of linseed oil and China-wood oil suchas the drying oils and so called semi-drying oils.

In place of zinc stearate, I can use aluminum oleate, lead stearate,lead oleate and zinc palmltate.

The mixture of linseed oil and China-wood oil can be varied within wide1imits,so long as no more than of the oil mixture is China-wood oil. Theproportions of these oils used is largely determined by their relativemarket price.

In the indicated formula the amount of linseed oil can vary from -400gallons and the same variation can be made with China-wool oil. Glossoil can vary from 60-180 gallons.

The amount of wax in the completed formula can vary from 1-l0%. Belowone percent, no polishing effect can be obtained and in excess of 10%,the gumminess and stickiness is increased to an unfavorable extent.

The zinc stearate can be varied in the formula From the abovedescription, it will be seen that I provide a fioor finish that containsa skin forming oil, a wax, a crystallizable salt and volatile solventthat will keep these ingredients in solution at room temperatures whileapplying to the fioor.

In finishing new fioors, the floor should be first scraped or machinesanded and a filler applied. The finish may then be applied with a ragor waste and allowed to setl5 minutes. The excess should then be wipedoff and the floor left to dry for at least 12 hours or until the, finishis thoroughly dry. The floor can then be polished and a wax finish addedif desired.
